Using event history modeling, this study explored to what extent loans, grants, institutional aid, and work-study affect timing to first departure for Latino college students. The goal is to understand more about how aid promotes or perturbs success for Latino students as well as how those effects vary over time. Federal grants and targeted loans reduced likelihood of departure (attrition). Findings suggest that aid is a necessary but not sufficient condition for success.
